The existence of a large border effect is considered as one of the main puzzles of international macroeconomics. We show that the border effect is, to a large extent, an artefact of geographic concentration. In order to do so we combine international flows with intranational flows data...

Previous studies have shown that, not only countries, but also regions have a preference to trade within their administrative borders. Using unique trade flows data, we also find a large home bias in Spanish intranational trade. However, we show that this home bias disappears once we take into...

To estimate correctly the effect of variable trade costs on firms’ exports, the gravity equation should control for the number of firms that participate in foreign markets. Due to the absence of these data, previous studies control for this omitted variable using econometric strategies that...

In this paper we use network-analysis tools to identify communities in the web of exporters' destinations. Next we use our network-based community measure as predictor of additional countries chosen by firms expanding their export destination portfolio. We defend that our network-based community...

The literature shows that new exporters have small levels of exports relative to regular exporters upon entry, and, if they survive, they have very high export growth rates between the entry year and the next year. However, these empirical facts might be biased by the partial year effect: firms...

Previous studies have shown that, not only countries, but also regions have a preference to trade within their administrative borders. Using unique trade flows data, we also find a large home bias in Spanish intranational trade. However, we show that this home bias tends to disappear once we...

This paper analyzes whether complexity, measured by the number of skilled tasks that are performed simultaneously in production, explains countries' commodity trade structure. We modify Romalis (2004) model to incorporate differences in complexity across commodities together with differences in...

To estimate correctly the effect of variable trade costs on firms' exports, the gravity equation should control for the number of firms that participate in foreign markets. Due to the absence of these data, previous studies control for this omitted variable using econometric strategies that may...

In this paper we use network-analysis tools to identify communities in the web of Bulgarian and Mexican exporters' destinations. We show that the network-based community measure is superior to extended gravity measures to predict the dynamics of firm's export-portfolio. This superiority stems...
